Low tire pressure leads to rapid and uneven wear of the tread, impairs vehicle handling, increases fuel consumption and, in addition, makes tires more likely to fail due to overheating.
Tires with excessively high air pressure impair the ride of the vehicle and are more prone to damage from hitting road bumps, potholes, etc. In addition, excessively high air pressure in tires causes uneven tread wear.
It is recommended to visually check the air pressure in the tires daily before driving. If you notice that the tire pressure has dropped, immediately check the air pressure with a tire pressure gauge.
Check the air pressure in all tires with a tire pressure gauge at least once a month. Even in fully serviceable tires, air pressure can drop by 10-20 kPa in a month. Remember to check the air pressure in the spare tire at the same time as checking the other wheels.
Air pressure is checked only on cold tires. The tires can be considered cold if the vehicle has been stopped for at least three hours or if the vehicle has been parked for a period of time less than 1.6 km. Inflate the tire or, if necessary, bleed some of the air out of it to bring the pressure up to the pressure indicated on the plate attached to the pillar of the doorway on the driver's side.
After driving a car for a distance of several kilometers, the tires have time to heat up, and the air pressure in them increases by 30-40 kPa compared to the cold state. This is quite normal. Do not reduce the air pressure in warm tires to bring it to the nominal value that is set for cold tires. Otherwise, the tires will run at reduced air pressure.
You should purchase and have your own tire pressure gauge in your vehicle, which you should use when checking tire pressure at all times. Keep in mind that tire pressure gauges work with a noticeable error and give a certain spread in readings, so it is preferable to constantly use the same measuring device. In this case, you will be able to notice a tire failure in time: the detected slight decrease in air pressure in the tire can be attributed with great certainty to damage to the tire, and not to differences in the readings of pressure gauges.
Tubeless tires have a certain ability to recover from small punctures. Since air leakage is often very slow, if a gradual decrease in air pressure is detected in the tire, it is necessary to carefully examine it, paying attention to the presence of foreign objects embedded in the tread.
For convenience, a plate is fixed on the front of the driver's door opening, which indicates the size of the tires and the standard air pressure in them.
